Correlation Between Capacity and Conductance of VRLA;

Under condition of that the state-of- charge for VRLA was higher than 50%, the difference of the internal resistance was too small, however the product of it s eletrochemical reactive resistance and electrical double layer capacitance was very sensitive to state.

Analysis of failed sealed lead acid battery;

Application of IC-UC3906 in sealed lead acid battery charger;

This paper presents the voltages variation possibitity of the sealed lead acid battery in different discharges.

Methods to identify if sealed lead-acid battery is dangerous goods;

Development of sealed lead-acid battery for starting application;

Since middle 1990s, the sealed lead-acid battery has been applied to motorcycle with motorcycle industry development and shown many advantages, but its performance did not meet the high requirement of motorcycle.

Effect of organic additives on the performance of sealed lead-acid batteries;

This paper describes an improved charging method for sealed lead-acid batteries using the UC3906.

2Ah sealed lead-acid batteries with grids of four different compositions of alloys were collected and examined.

The causes of formation on PCL of VRLA batteries were analyzed, skills of AGM separators in VRLA batteries was supposed.

Some parts of VRLA batteries such as grid,container,cover and valve are optimized in this paper according to the common problems occurred in the use of VRLA batteries.

Also,according to actual operation and maintenance,main points concerning life length of valve regulated lead acid battery were introduced which provided reference to the use of the battery.

Maintenance and management of communication valve regulated lead acid battery;
